Monitoring device of an inductive sensor of a mechanical rope lift line

Abstract

Monitoring device of an inductive sensor of a mechanical rope lift line A monitoring device of an inductive sensor of a mechanical ropeway comprises support means securedly affixed to a sheave assembly with sheaves associated with a pylon. The device comprises an actuating ramp arranged on a test carriage and able to make the sensor go from a first position detecting presence of the rope to a second position detecting absence of the rope. The support means of the sensor comprise a fixed part securedly affixed to the corresponding sheave assembly, and a movable part mounted pivoting with respect to the fixed part and operating in conjunction with the actuating ramp of the test carriage to incline the sensor to the second position detecting absence of the rope when the test carriage passes.

1 . A monitoring device of at least one inductive sensor of a line of a mechanical ropeway, the device comprising first support means of the sensor securedly attached to a sheave assembly with sheaves associated with a pylon of the line, and second means able to make the gap between the rope and sensor vary,
 a device wherein:
 the second means to make the gap vary comprise an actuating ramp arranged on a test carriage designed to operate in conjunction with the monitoring device to make the sensor go from a first position detecting presence of the rope to a second position detecting absence of the rope, 
 the first support means of the sensor comprise a fixed part securedly attached to the corresponding sheave assembly, and a movable part mounted pivoting with respect to the fixed part and operating in conjunction with the actuating ramp of the test carriage to incline the sensor from the first position detecting presence of the rope to the second position detecting absence of the rope. 
   
   
   
       2 . The device according to  claim 1 , wherein the fixed part of the first support means comprise a jointed plate having a first side fixed on the sheave assembly and parallel to the sheaves, and a second side perpendicular to the first side and provided at the end thereof with a swivel pin articulating the movable part of the support means. 
   
   
       3 . The device according to  claim 1 , wherein the movable part of the first support means comprises:
 a salient portion with a rounded edge along which the actuating ramp of the test carriage presses and slides,   securing means of the sensor designed to raise the sensor with respect to the fixed part and to place the sensor near the rope in the first position detecting presence of the rope.   
   
   
       4 . The device according to  claim 1 , comprising flexible return means of the movable part of the first support means of the sensor from the position detecting absence of the rope to the position detecting presence of the rope. 
   
   
       5 . The device according to  claim 1 , associated with a support sheave assembly and/or with a compression sheave assembly of a pylon of the mechanical lift line. 
   
   
       6 . The device according to  claim 5 , and associated with a support sheave assembly, wherein:
 the securing means of the sensor are arranged between two adjacent sheaves of the sheave assembly,   the sensor is placed under the rope in alignment with the sheaves of the sheave assembly in the first position detecting presence of the rope, and inclined with respect to the sheaves in the second position detecting absence of the rope.   
   
   
       7 . The device according to  claim 5 , and associated with a compression sheave assembly, wherein:
 the securing means of the sensor are salient away from the sheaves,   the sensor is placed facing the rope in a plane parallel to the sheaves of the sheave assembly in the first position detecting presence of the rope, and inclined with respect to the sheaves in the second position detecting absence of the rope.   
   
   
       8 . The device according to  claim 5 , wherein the actuating ramp of the test carriage comprises a bottom ramp and a top ramp operating in conjunction with the movable part of the associated support means of the sensor respectively with a support sheave assembly and with a compression sheave assembly.
